Casa en Río Cedro is a completely open-air, two-story <a href="http://inhabitat.com/partially-furry-glass-cube-uses-tradition-palapa-as-a-sustainable-facade/">palapa</a> home that proves walls are not a necessity.

Sustainably harvested wood was used throughout to avoid contributing to the deforestation of native forests that is ongoing in the area.
